Tetsunosuke Ichimura (市村 鉄之助,Ichimura Tetsunosuke?) is the protagonist of Peacemaker Kurogane. He is short, strong-willed, and often underestimated by his peers. Tetsu also has a cheerful, active and competitive personality. He joins the Shinsengumi in order to become strong and avenge the death of his parents at the hands of a member of the Chōshū clan, and ends up working as a page to Hijikata. At the time in 1864, Tetsu had psychogenic dwarfism and has not grown physically for two years due to his emotional scar. He has been more-or-less adopted as a mascot/little brother figure by the senior members of the Shinsengumi. He cries a lot and has a good relationship with Saya.
